Title: Magnetic position indicator
IPC: G21C17/12
Filed: 1973-01-22
Abstract: 1416895 Position transducers M GERIN 22 Jan 1973 [24 Jan 1972 25 April 1972] 3198/73 Heading H3H [Also in Division. G1] Apparatus for indicating the position of a movable core member 10 comprises a plurality of pairs of series-opposition connected secondaries 18, 20-26, 28 disposed along a path 12 of movement of the member 10, the secondaries being arranged to provide a null output when the coupling between the members of a pair with a single primary 14 is equal, i.e. when the core 10 is wholly within or wholly without the two members forming a pair, and a positive output when this coupling is unequal. The number of turns of the secondaries may vary pair-wise along the path 12 so that the first pair each have 8 turns and the next 2s and so on. The outputs from each pair are each taken via a resistor to the input of a summing amplifier, and in this embodiment, by making all the resistance values equal, the voltage at the output of the amplifier is indicative of the position of the end of the core 10. Alternatively the turns may be equal in all of the pairs and the resistances may be of different values. In a further embodiment, the outputs from the secondary pairs are taken to respective threshold devices which when activated open a gate to either allow a current from a particular tap of a potential divider to flow to a summing amplifier, or allow current to pass through a particular resistor to the amplifier. The threshold devices may be linked to their neighbours by potentiometers whereby both of two adjacent threshold devices may be activated for certain positions of the core 10. A detector detects this multiple activation and causes an additional resistance to be introduced so that the mean value of the current of the two stages passes to the amplifier. In a further embodiment, the pairs of secondaries are not formed by adjacent windings as shown in Fig. 1 but are connected so that a 3-bit Gray code is produced indicative of discrete positions of the member 10.

Title: Improvements in or relating to follow-up control systems
Inventor: WALKER JOHN RUSSELL DUGUID
IPC: F15B9/03
Filed: 1952-02-11
Abstract: 748,073. Electric follow-up systems. VICKERS-ARMSTRONGS (ENGINEERS), Ltd. May 30, 1952 [Feb. 11, 1952], No. 3571/52. Class 40(1) [Also in Group XXIX] In a gun-mounting follow-up system, the mounting is moved by a hydraulic swashplate motor, the torque of which is determined by the angulation of the swashplate. An electric signal proportional to the director setting, developed by a magslip system, controls the hydraulic servosystem which positions the swash-plate. A speed governor, limit stops hydraulic braking and parking brakes are incorporated. In one embodiment, Fig. 1, the load 3 on shaft 2 is moved by the hydraulic motor 1, the swash-plate of which is adjusted by the servo system 7, 31., 40. The output of the latter is determined by the electrical error signal applied to it at 24 and derived from the magslip system 10, 12, 14, 15. In a modified system, not shown, the swash-plate movement is controlled by the servo-system Fig. 3. In this, the swash-plate lever 4 is moved by the action of H.P. fluid in the cylinder 115 on the piston 116. The supply of H.P. fluid to the cylinder is controlled by valve 70, which is moved by fluid, at intermediate pressure, controlled by piston 44, which is moved in accordance with the magslip signal applied at 24. The supply of I.P. fluid to 70 is cut-off by the follow-up member 45 moved by the inclined surface 99 of 70. The supply of H.P. fluid to 115 is cut-off by the movement of follow-up plunger 83 moved by the wedge 88 of piston 116. Emergency operation. Hydraulic braking is effected by plunger 101 which directs the flow of H.P. fluid to the swash-plate control cylinder so as t o cause motor 1 to oppose the motion of the mounting. In an emergency or when the mounting operates the limit stops, plunger 101 is clutched to the shaft 2 electrically, a blocking valve stops the supply of fluid to the motor 1 and a parking brake is applied to shaft 2. Should the amount of fluid in the accumulator fall to a low level, the supply to the motor 1 is checked and the residual fluid is available to drive the servo-system for braking purposes. Overspeeding is prevented by means of a tachometer generator' driven by shaft 2, the signal from which opposes the action of the error signal at 24.

Title: Pipe storing rack
IPC: B65G1/04
Filed: 1973-01-24
Abstract: 1424130 Pipe storing rack MITSUI SHIPBUILDING & ENG CO Ltd 24 Jan 1973 [25 Jan 1972] 3611/73 Heading B8M [Also in Division A4] A pipe storing rack has a vertical space 13 for storing pipes 7 in horizontal superimposed relation, a pipe discharge outlet 4 communicating with the end of the space 13 and into which the pipes drop, the outlet 4 having an upward projection 8 which normally stops the discharge of the lowest pipe 7a, and means, e.g. a jack 12, for raising the lowest pipe 7a in the outlet 4 is that it clears the projection 8 and is discharged by the weight of the other pipes bearing thereon. The raising of the jack 12 prevents discharge of further pipes until this is done by the projection 8. In a preferred embodiment, several rack units are provided on a single frame whereby different pipes may be received in the separate spaces 13 and selectively discharged. In this case, the outlet 4 is formed between adjacent plates 5 provided beneath the frame 2; the plates 5 being suitably shaped to provide two arcuate sections 6 and 10 and a declerating step 9. The pipes are loaded into the spaces 13 by means of a container 14 which is open at the bottom and also at one side, removable bars holding the pipes within the container, which bars extend from top to bottom of the open side. The pipes are held in the container by means of pins 17 extending into the bore of the lowest pipe 7b, the pins 17 being retracted when the weight of the pipes in the container is taken by pipes 7 in the space 13 or by the arcuate section 6 of the outlet 4. The container 14 is then removed from the space 13 by a crane or similar hoist.

Abstract: 1351402 Colour television SONY CORP 26 Jan 1972 [29 Jan 1971] 3746/72 Heading H4F In a PAL demodulator system, Fig. 4, the chrominance signal, Fig. 3, is passed to demodulators 2 and 3 via a direct path comprising switched diode 12, or a delayed path via one line period delay 10 and switched diode 13. The operation of the diode switching and the associated control means 11, 14, 15 is such that every other line is fed twice in succession to the demodulators, i.e. a line, e.g. 7th is fed via diode 12 to the demodulators and is then fed again in the next line interval via the delay 10 and diode 13-a typical line sequence to the demodulators being: 7, 7, 9, 9, 11, 11 ... The demodulators are thus fed with signals having a constant carrier phase, i.e. the "phase alternating line" is compensated for. The constant phase is + or - ve depending on the relative phase of the switching action of circuit 11 and it is the purpose of the invention to make said constant phase always + ve or - ve whenever and however the system is enabled, independent of the four frame cycle undergone by the burst blanking period B B  in its wandering through the interfield spaces. The gated out bursts Fig. 5A, are rectified at 14 to give waveform 5B which, after differentiation at 15 gives waveform 5C. The positive spikes S 2  cause the high conduction of transistor 16 and the production of waveform 5D at its collector. A capacitor 19 charges up during the periods between the negative going pulses and also in the burst blanking interval to give waveform 5E. A transistor 22 conducts at a predetermined threshold of time t 1  and produces, until the end t 2  of the burst blanking interval, a switching pulse 5F for the bi-stable circuit 11 producing the diode switching pulses, the circuit 11 thereby always being in the correct state at the beginning of the ensuing field to give the bursts of the required phase.

Abstract: 840,482. Stapling machines. ELASTIC AKTIENGESELLSCHAFT VORM. M. VOGEL A. G. Feb. 7, 1958 [Feb. 11, 1957], No.4111158. Class 89(3) In a stapling machine, a feed brush 12 simultaneously engages a plurality of webs of the staples 6 in the magazine and is caused to move towards the expelling channel during operation of the staple expeller 4 to feed the staples 6 towards the expelling channel. In Fig. I the feed brush 12 is carried by a slidable bar 8 which is retracted against a spring 10 during the driving movement of the expeller 4 due to co-operation between cam surfaces 14, 15 on the bar 8 and expeller 4 respectively. During the return movement of the expeller 4 the surface 15 releases the bar 8 which is then moved in a feeding direction by the spring 10 so that the brush 12 feeds the staple strip 6 towards the expelling channel. The bristles of the brush 12 are inclined with their free ends nearer to the expelling channel than their opposite ends. To prevent movement of the staple strip during rearward movement of the brush 12, fixed brushes 16 which engage opposite end portions of the staple webs, or a fixed brush 16, Fig. 3, bearing against the underside of the staple webs are provided.
